Metropolitan Community College in Nebraska failed to comply with numerous provisions of federal financial aid rules and should be forced to repay at least $233,000 to the government, the U.S. Education Department's inspector general said in an audit this month. Among other things, the agency said, the two-year college improperly disbursed federal aid to students who did not have high school diplomas or had not passed ability-to-benefit tests, to students who exceeded the maximum number of allowable credit hours of remedial coursework, and students who did not satisfy academic progress requirements. College officials disputed some of the inspector general's findings, which will go to Education Secretary Arne Duncan for potential action.
